AOL closed the domain down on Halloween, 2008, so the List was carried over to the www.polychora.com domain in early November, 2008. The final visitor count before AOL Hometown was closed down was 93661, on October 30, 2008. List last updated 12/15/17 Additions and corrections entered since the last update are in green.

Occasionally it is found that two different names have been given to the same genus. Such names are known as synonyms, and instances of synonymy are annotated in the List (see Synonymies in List section below). Being a synonym by no means invalidates a generic name, since the junior synonym is usually available in case a synonymy is refuted or the senior synonym is found to be preoccupied. The names appear in this List without regard to their validity or synonymy, but each name is associated in some way, formally or informally, with real fossil material. Names of dinosaur footprint and egg genera, however, or of fictional, fictitious, or fraudulent dinosaurs, are not included. Published Japanese common names, usually ending in “-ryu,” are not included unless they have been Latinized elsewhere in print. Also not included are names that have appeared solely on the Internet, or in e-mails, in advance of publication (there are usually four or five such floating around at any particular time). Author(s) and year of publication are provided for each name, to facilitate locating original references. For more information on any genus, simply enter its name into a Google search, or subscribe to Tracy Ford’s Paleofile website. Different authors with the same surname are distinguished by their initials or by entire first names if initials are not sufficient. Prior to August 2007, the List did this haphazardly, particularly for Oriental authors, but thanks to bibliographic research by Rob Taylor, I was able to make the entries quite consistent throughout, with only a few remaining ambiguities (we are working on them). Also, when an author has used different surnames in different references, I provide a consistent surname throughout but indicate in parentheses the surname as it appears in the description, when it is different. Chinese and Korean authors are standardly listed surname first, regardless of how their names were cited. This should facilitate using the List in computer searches by author. Because there are many, I have not indicated these changes with green text. A few typos may persist in the additions for a while until they are caught and weeded out. For the purposes of this List, a dinosaur is defined as any archosaur more closely related to modern birds than to modern crocodylians that is not itself a true bird. I call the stem-based clade of archosaurs more closely related to modern birds than to modern crocodylians Ornithes, the clade of modern birds Aves (by tradition, the common ancestor of all extant birds together with all its descendants), and the clade of true birds Avialae (by tradition, the common ancestor of modern birds and Archaeopteryx together with all its descendants). If dinosaurs were defined here as a clade instead of as the difference between two clades, then all birds would be dinosaurs, and the Dinosaur Genera List would be obliged to include the names of thousands of fossil and extant bird genera along with the names of the genera that most of us are accustomed to calling dinosaurs: interesting, but probably not what one might be looking for as a list of dinosaur names. So, according to this scheme, dinosaurs become “non-avialan ornithans.” But note that this definition also includes what have been termed “pre-dinosaurs,” or “dinosaur precursors,” that is, archosaurs on the stem that joins the common ancestor of crocodylians and birds to the most basal known dinosaurs. So far, no convincing (to me) dinosaur precursors have been identified in the fossil record, although many consider the lagosuchians from South America, and some others, to be such. The successively more inclusive clades Dinosauriformes Novas, 1992 and Dinosauromorpha Benton, 1985 have been created to include these forms as outgroups to Dinosauria, so those archosaurs become “non-dinosaurian dinosauriforms” and “non-dinosauriform dinosauromorphs.” To me, this is outrageous hairsplitting, particularly since the forms in these groups are few in number and most appear to me to be basal theropods rather than basal dinosaurs. Until more convincing arguments are published on why such forms should not be called dinosaurs, I’ll retain them in the Dinosaur Genera List without further annotation. Perhaps later, when I perform a List overhaul, I may annotate them as “precursor dinosaurs.” file://C:\Documents and Settings\George\Desktop\Paleo Papers\dinolist.html 12/15/2017 Dinosaur Genera List Page 4 of 42 This is the Mother of All Internet Dinosaur Lists. It was first posted to the Dinosaur Mailing List (see archive) on October 23, 1995. Thereafter, it was gradually corrected and tuned to weed out misspellings and other inappropriate generic names, eventually evolving into its present form. Before October 1995, there was simply no complete list of dinosaur genera available on the Internet; all the other Internet dinosaur lists, some with much additional information, sprang up after this one became available. The initial Dinosaur Genera List tabulated 770 names, after a few non-dinosaurian genera that had crept in were removed. The entire List was published as part of The Dinosaur Folios #1 in May 1996, when it had grown to 787 names long. It was also published in 1997, when the name count stood at 806, at the back of Encyclopedia of Dinosaurs (P. Currie & Padian, eds.). On or about May 24, 1997, the entire List, with the name count at 805, was posted on the Dinogeorge website home page. There it remained until it became the present separate web page on December 3, 2000, with the name count at 895. The Dinosaur Genera List is freely available to anyone who desires to publish it in book or magazine form, to link to it, or to display it at a website, provided only that George Olshevsky be informed of such publication or Internet display, and be properly credited as compiler. Maximize screen for best viewing/reading. What are genera? Genus (plural: genera) is a major category invented in the mid-1750s by the botanist Carolus Linnaeus (or Karl von Linne) for his system of classifying nature. His Systema Naturae is still, more than 250 years later, in use by naturalists and biologists worldwide. The lowest-ranking major category is the species, and the genus is the next lowest-ranking major category.

  • A Novel Form of Postcranial Skeletal Pneumaticity in a Sauropod Dinosaur: Implications for the Paleobiology of Rebbachisauridae
    Editors' choice A novel form of postcranial skeletal pneumaticity in a sauropod dinosaur: Implications for the paleobiology of Rebbachisauridae LUCIO M. IBIRICU, MATTHEW C. LAMANNA, RUBÉ N D.F. MARTÍ NEZ, GABRIEL A. CASAL, IGNACIO A. CERDA, GASTÓ N MARTÍ NEZ, and LEONARDO SALGADO Ibiricu, L.M., Lamanna, M.C., Martí nez, R.D.F., Casal, G.A., Cerda, I.A., Martí nez, G., and Salgado, L. 2017. A novel form of postcranial skeletal pneumaticity in a sauropod dinosaur: Implications for the paleobiology of Rebbachisauridae. Acta Palaeontologica Polonica 62 (2): 221–236. In dinosaurs and other archosaurs, the presence of foramina connected with internal chambers in axial and appendic- ular bones is regarded as a robust indicator of postcranial skeletal pneumaticity (PSP). Here we analyze PSP and its paleobiological implications in rebbachisaurid diplodocoid sauropod dinosaurs based primarily on the dorsal verte- brae of Katepensaurus goicoecheai, a rebbachisaurid from the Cenomanian–Turonian (Upper Cretaceous) Bajo Barreal Formation of Patagonia, Argentina. We document a complex of interconnected pneumatic foramina and internal chambers within the dorsal vertebral transverse processes of Katepensaurus. Collectively, these structures constitute a form of PSP that has not previously been observed in sauropods, though it is closely comparable to morphologies seen in selected birds and non-avian theropods. Parts of the skeletons of Katepensaurus and other rebbachisaurid taxa such as Amazonsaurus maranhensis and Tataouinea hannibalis exhibit an elevated degree of pneumaticity relative to the conditions in many other sauropods. We interpret this extensive PSP as an adaptation for lowering the density of the skeleton, and tentatively propose that this reduced skeletal density may also have decreased the muscle energy required to move the body and the heat generated in so doing.

The Late Triassic Thecodontosaurus antiquus occupies a basal position within Sauropodomorpha, being a key taxon for documenting how those morphofunctional transitions occurred. Here, we redescribe the braincase osteology and reconstruct the neuroanatomy of Thecodontosaurus, based on computed tomography data. The braincase of Thecodontosaurus shares the presence of medial basioccipital components of the basal tubera and a U-shaped basioccipital–parabasisphenoid suture with other basal sauropodomorphs and shows a distinct combination of characters: a straight outline of the braincase floor, an undivided metotic foramen, an unossified gap, large floccular fossae, basipterygoid processes perpendicular to the cultriform process in lateral view and a rhomboid foramen magnum. We reinterpret these braincase features in the light of new discoveries in dinosaur anatomy. Our endocranial reconstruction reveals important aspects of the palaeobiology of Thecodontosaurus, supporting a bipedal stance and cursorial habits, with adaptations to retain a steady head and gaze while moving.

We conclude that these fossil remains represent a bipedal heterodontosaurid but lack diagnostic characters to identify them at the species level, although they probably represent remains of Manidens condorensis, known from the same locality. Histological features suggest a subadult ontogenetic stage for the individual. A cluster analysis based on pedal measurements identifies similarities of this specimen with heterodontosaurid taxa and the inclusion of the new material in a phylogenetic analysis with expanded character sampling on pedal remains confirms the described specimen as a heterodontosaurid. Finally, uncommon features of the digits (length proportions among nonungual phalanges of digit III, and claw features) are also quantitatively compared to several ornithischians, theropods, and birds, suggesting that this may represent a bipedal cursorial heterodontosaurid with gracile and grasping feet and long digits.

Rivadavia 1917 - Cdad. de Buenos Aires, Argentina (Received 28 November 2008; revised 09 July 2009; accepted 14 July 2009) ABSTRACT The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks (approximately 230 Ma) accumulated over extensional rift basins in southwestern Pangea. The better known of these are Herrerasaurus ischigualastensis, Pisanosaurus mertii, Eoraptor lunensis,andPanphagia protos from the Ischigualasto Formation, Argentina, and Staurikosaurus pricei and Saturnalia tupiniquim from the Santa Maria Formation, Brazil. No uncontroversial dinosaur body fossils are known from older strata, but the Middle Triassic origin of the lineage may be inferred from both the footprint record and its sister-group relation to Ladinian basal dinosauromorphs. These include the typical Marasuchus lilloensis, more basal forms such as Lagerpeton and Dromomeron, as well as silesaurids: a possibly monophyletic group composed of Mid-Late Triassic forms that may represent immediate sister taxa to dinosaurs. The first phylogenetic definition to fit the current understanding of Dinosauria as a node-based taxon solely composed of mutually exclusive Saurischia and Ornithischia was given as ‘‘all descendants of the most recent common ancestor of birds and Triceratops’’.

  • Brains and Intelligence
    BRAINS AND INTELLIGENCE The EQ or Encephalization Quotient is a simple way of measuring an animal's intelligence. EQ is the ratio of the brain weight of the animal to the brain weight of a "typical" animal of the same body weight. Assuming that smarter animals have larger brains to body ratios than less intelligent ones, this helps determine the relative intelligence of extinct animals. In general, warm-blooded animals (like mammals) have a higher EQ than cold-blooded ones (like reptiles and fish). Birds and mammals have brains that are about 10 times bigger than those of bony fish, amphibians, and reptiles of the same body size. The Least Intelligent Dinosaurs: The primitive dinosaurs belonging to the group sauropodomorpha (which included Massospondylus, Riojasaurus, and others) were among the least intelligent of the dinosaurs, with an EQ of about 0.05 (Hopson, 1980). Smartest Dinosaurs: The Troodontids (like Troödon) were probably the smartest dinosaurs, followed by the dromaeosaurid dinosaurs (the "raptors," which included Dromeosaurus, Velociraptor, Deinonychus, and others) had the highest EQ among the dinosaurs, about 5.8 (Hopson, 1980). The Encephalization Quotient was developed by the psychologist Harry J. Jerison in the 1970's. J. A. Hopson (a paleontologist from the University of Chicago) did further development of the EQ concept using brain casts of many dinosaurs. Hopson found that theropods (especially Troodontids) had higher EQ's than plant-eating dinosaurs. The lowest EQ's belonged to sauropods, ankylosaurs, and stegosaurids. A SECOND BRAIN? It used to be thought that the large sauropods (like Brachiosaurus and Apatosaurus) and the ornithischian Stegosaurus had a second brain.

  • A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)
    A PHYLOGENETIC ANALYSIS OF THE BASAL ORNITHISCHIA (REPTILIA, DINOSAURIA) Marc Richard Spencer A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE December 2007 Committee: Margaret M. Yacobucci, Advisor Don C. Steinker Daniel M. Pavuk © 2007 Marc Richard Spencer All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor The placement of Lesothosaurus diagnosticus and the Heterodontosauridae within the Ornithischia has been problematic. Historically, Lesothosaurus has been regarded as a basal ornithischian dinosaur, the sister taxon to the Genasauria. Recent phylogenetic analyses, however, have placed Lesothosaurus as a more derived ornithischian within the Genasauria. The Fabrosauridae, of which Lesothosaurus was considered a member, has never been phylogenetically corroborated and has been considered a paraphyletic assemblage. Prior to recent phylogenetic analyses, the problematic Heterodontosauridae was placed within the Ornithopoda as the sister taxon to the Euornithopoda. The heterodontosaurids have also been considered as the basal member of the Cerapoda (Ornithopoda + Marginocephalia), the sister taxon to the Marginocephalia, and as the sister taxon to the Genasauria. To reevaluate the placement of these taxa, along with other basal ornithischians and more derived subclades, a phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, was performed. Analysis of 97 characters and their associated character states culled, modified, and/or rescored from published literature based on published descriptions, produced four most parsimonious trees. Consistency and retention indices were calculated and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny. The Ornithischia was recovered with Pisanosaurus as its basalmost member.

  • The Sauropodomorph Biostratigraphy of the Elliot Formation of Southern Africa: Tracking the Evolution of Sauropodomorpha Across the Triassic–Jurassic Boundary
    Editors' choice The sauropodomorph biostratigraphy of the Elliot Formation of southern Africa: Tracking the evolution of Sauropodomorpha across the Triassic–Jurassic boundary BLAIR W. MCPHEE, EMESE M. BORDY, LARA SCISCIO, and JONAH N. CHOINIERE McPhee, B.W., Bordy, E.M., Sciscio, L., and Choiniere, J.N. 2017. The sauropodomorph biostratigraphy of the Elliot Formation of southern Africa: Tracking the evolution of Sauropodomorpha across the Triassic–Jurassic boundary. Acta Palaeontologica Polonica 62 (3): 441–465. The latest Triassic is notable for coinciding with the dramatic decline of many previously dominant groups, followed by the rapid radiation of Dinosauria in the Early Jurassic. Among the most common terrestrial vertebrates from this time, sauropodomorph dinosaurs provide an important insight into the changing dynamics of the biota across the Triassic–Jurassic boundary. The Elliot Formation of South Africa and Lesotho preserves the richest assemblage of sauropodomorphs known from this age, and is a key index assemblage for biostratigraphic correlations with other simi- larly-aged global terrestrial deposits. Past assessments of Elliot Formation biostratigraphy were hampered by an overly simplistic biozonation scheme which divided it into a lower “Euskelosaurus” Range Zone and an upper Massospondylus Range Zone. Here we revise the zonation of the Elliot Formation by: (i) synthesizing the last three decades’ worth of fossil discoveries, taxonomic revision, and lithostratigraphic investigation; and (ii) systematically reappraising the strati- graphic provenance of important fossil locations. We then use our revised stratigraphic information in conjunction with phylogenetic character data to assess morphological disparity between Late Triassic and Early Jurassic sauropodomorph taxa. Our results demonstrate that the Early Jurassic upper Elliot Formation is considerably more taxonomically and morphologically diverse than previously thought.

Basal titanosauriforms were present in Japan during the Early Cretaceous before Aptian, and there is the possibility that the Brachiosauridae may have been included. Basal titanosauriforms with peg-like teeth were present during the “mid” Cretaceous, while the Titanosauria with peg-like teeth was present during the middle of Late Cretaceous. Recent excavations of Cretaceous sauropods in Asia showed that multiple lineages of sauropods lived throughout the Cretaceous in Asia. Japanese fossil records of sauropods are conformable with this hypothesis. Key words: Sauropod, Titanosauriforms, tooth, Cretaceous, Japan.
